A VP includes an EPB system configured to switch between activation and release of brakehold and a VCIB that interfaces between an ADS and a VP. The VCIB is configured to provide a standstill status signal to the ADS. The standstill status signal includes a value applied indicating activation of brakehold and a value released indicating release of brakehold. The ADS includes a compute assembly. When the compute assembly requests the VP to activate brakehold, it requests the VP to decelerate until the standstill status signal switches from the value released to the value applied.
